UNITED STATES PATENT oFFicE..

BRACKET.

Application filed April 11, 1927, Serial No. 182,939, and in Canada May 13, 1926.

My invention relates to improvements in brackets, the olnects ot which are to provide ,means whereby bearers lor scaffolding shelvesv upon it.

The invention consists essentially ot' a strip of metal having a semi-cylindrical medial portion which is slotted to receive one encl of a suitable bearer, as will be more fully described in the following specication in which Fig. l is a front view of the invention.

Fig. 2 is a plan view showing a bearer in position.

Fig. 3 is a general view of the invention as applied to a wall to be plastered and showing` a bearer (in dotted line) in the slot.

In the drawings like characters of reterence indicate corresponding parts in each gure.

The numeral l indicates a wall surface of ship -la p though the device is applicable equally well to a wall of any other construction, to which the bracket generally indicated by the numeral 2 is nailed as at 3. The bracket 2 is formed of a strip of metal 4c having a semicylindrical portion 5 of such projection as to be easily covered by the finish coat of plaster or stucco. The portion 5 is provided with a slot 6 extending downwards from its upper extremity for the greater portion of `its length, the slot 6 being preferably of somewhat less width than the bearer 7 to be fitted thereto, so that as the bearer is pressed down into the slot the edges oi the strip are caused to cut slightly into the wood of the bearer in extent according to the pressure exerted by by the metal from which the bracket is made and to grip the bearer firmly at its lower edge and sides. Obviously in scaifolding or temporary Work, the outer end of the bearer is suitably supported to bear its part of the superposed load. In scaffolding a Wall to be plastered or coated with stucco, see Figure 3, the ship-lap Wall l is strapped with vertical strapping 8 which is in turn covered with laths 9 the laths being butted up close tothe bracket 2 as at l0, the first coat oitl plaster is then applied as at 11, the plaster being brought close up to the scaffold bearers 7. TWhen the iirst or rendering coat oit plaster has been applied the floating or rough cast Coat is put on, starting from the top of the wall and working downwards in the usual way. As each row of brackets 2 are reached the scailoldinc' is removed and the bearers 7 are detached from their outer supports and as a downward pull is exerted upon them their hold in the slots 6 will be broken, permitting them to be removed without diiilculty. .It then suffices to lill in the semi-cylindrical portion and the slot ot' the bracket with cement or plaster and to continue the floating coat completely covering the bracket from view. lhen the brackets are used i'or shelving or other permanent work the upper edge of the bearer is preferably skew nailed to the Wall and the plaster brought down into Contact therewith, when sutlicient hold is provided to hold the bearer against removal.

It will thus be seen that I have invented a bracket tor'scall'olding or shelving which is simple and economical in manufacture and which is easily secured to a wall surface and capable otl securely holding a suitable bearer without extraneous tastenings.

IV hat I claim as my invention is:

The combination with a scallold bearer or the like, ot' a bracket adapted for attachment to a wall surface, said bracket being formed of? inherently springy sheet material and having medial portions curved away from the wall surface to detine a vertical slot into which the end of a bearer is adapted to be supported, said slot being of a width less than that of the bearer whereby, said medial por tions are caused to exert a resilient gripping pressure on the side of the bearer.
